View of the inside of the carb with the top removed.  This shot is after the throttle shaft, throttle plate, and accelerator pump components have been reinstalled.  The bright silver dot between the barrel and bowl is a lead plug.   There are a number of these are installed at various places on the carb body.   If a passage in the carb is clogged, and dipping doesn't clear up, you can remove these lead plugs easily with a soldering iron.  Replacement plugs can be picked up from a reloading store.  I used #4 and #1 buckshot.  To install the lead ball large then the size of the hole is tapped into place with a steel drift and hammer.   Then using a jewelers file, removed the protruding bit.  On the external portion of the body this is pretty easy, but use care when working on a gasket surface.

Some of the smaller bits.  To ensure that the passages were indeed clear, I removed some of the brass plugs also, one of which is on the upper right in this picture.  These can be carefully pried out with a screwdriver.  Then apply gentle heat to prevent work hardening of the brass.  I then used a a tapered steel rod to expand the opening of the plug to ensure it would be a tight fit when reinstalled. 

The nose surface of my idle jet was pretty hosed up.  It was cupped out and I believe this caused a gap wich prevented fuel from reaching the idle circuit.  I chucked the jet into a motor tool and working at a low speed, reshaped the nose of the jet.  This allowed for a better seat against the fuel port.

Looking down into the bowl.  At idle fuel is drawn through the Main Jet and up through the air tube.  There is a passage that runs horizontally from the air tube to the idle jet port.  The fuel enters the nose of the idle jet and exits out the three holes in the circumferance of the jet body into the idle jet port.   Here the fuel mixes with air.  The air enters through a hole in the roof of the port that leads to the idle circuit air inlet.

Here you can just make out the fuel inlet in the back of the port.  From here the air/fuel mixture continues through the idle circuit by entering a hole in the bottom of the port.

From the idle jet housing, the fuel continues straight down to the port that runs horizontal where the words "idle speed screw" are.  Where the "Idle" is, the mixture turns down again.  It goes down, past the transition circuit holes and into the idle screw chamber.  Behind the "I" and just below the "screw" are 2 more lead plugs.

Here, with the brass plug removed you can just make out the three small holes that make up the transition circuit.  These three holes are fed by the same fuel mixture as the idle circuit.  At idle the throttle plate is above the idle outlet and the transition outlet.  As the throttle is opened more, the transition circuit come into play.  For more details on the operations of the idle and transition circuits, check out the manuals section.

The acceleration circuit is pretty straight forward.  The accel pump draws fuel from the bowl through the accelerator jet.  It is then pushed out through the accelerator outlet.  This outlet can be easily pulled from the carb body.  It is held in place by a rubber O-ring.  A replace ment O-ring is contained in the kit.  These accelerator outlet nozzles come in different sizes, as do the accelerator jets.

Here you can see the housing that holds the inlet fuel filter, needle valve and float.
The float spacing is measured between the top of the float and the face of the carb top with the gasket installed.  The minimum distance is 6.5mm and the max is 13mm

A couple of views of the power valve assembly.  The power valve is explained in detail in the Weber pdf file in the manuals section.
